Problems solved by technology

Existing concentrators have done a lot of research on the transmission device and body structure, but there are few innovations in the design of underflow discharge. In addition, how to ensure that the agent and slime water are fully mixed and the degree of turbulence in the thickener body is small, how to ensure The thickener works stably, preventing the rake frame of the thickener from being "pressed" by high-concentration materials has become a research hotspot in this field in recent years

Abstract

The invention relates to the field of concentration treatment of coal slurry water, in particular to a quantitative dissolution and uniform mixing addition system of a flocculation agent. The system comprises an agent storage system, a quantitative agent conveying and addition system, an efficient agent dispersion system, a PLC (programmable logic controller) intelligent control system, an ore pulp and agent mixing system and a coal slurry water concentration and settling system, wherein the agent storage system and the quantitative agent conveying and addition system ensures addition of the powdered agent according to required dose; the efficient agent dispersion system achieves uniform dispersion and quick dissolution of the powdered agent in an aqueous solution; and the ore pulp and agent mixing system promotes uniform mixing of the aqueous solution in which the flocculation agent is dissolved, and the coal slurry water and has a good flocculation settling initial condition. A coredevice of the coal slurry water concentration and settling system is a three-section discharge harrow-less concentrator; the concentrator adopts a 'one-middle and two-sides' discharge mode; thick particles and fine particles are discharged and recovered through different ports; the fine particles have longer settling time; and a whole concentration task has higher concentration efficiency.

Description

technical field [0001] The invention relates to the field of coal slime water flocculation sedimentation and concentration treatment, in particular to a quantitative dissolution and uniform mixing addition system of flocculation agents. Background technique [0002] The vast majority of coal preparation plants in my country use wet coal preparation. Coal slime water treatment is an important link in the wet coal preparation process. From the perspective of economy and environmental protection, it is required to deeply clarify the slime water and wash water in a closed circuit. Coal preparation plants usually use coagulation method to process slime water. The so-called coagulation method is to add coagulant to the slime water system to make the particles in the slime water system reunite and settle by gravity. The commonly used coagulants are organic polymer flocculants, such as polyacrylamide. Due to the characteristics of large molecular weight and long side chains, organic...
